Along with the squeeze bottles are filter funnels. These are the Whatman brand that can normally only be sold by the hundred. Each: US$4. Filter papers for these are 1" diameter; we
recommend Whatman #4. Funnels are fit with the paper, then wrapped in foil and autoclaved. Seed is disinfected, and the filter is used to separate the seed from the disinfectant. The seed is then
washed (see wash bottles, above), and the paper removed with sterile forceps to be placed in flask. Alternatively, the seed may be scraped from the filter paper with a replate fork. One other
technique uses an additional squirt of sterile water to suspend the seed, which is then poured into the flask for sowing. These funnels may be autoclaved repeatedly. Inquire about availability of
filter papers.

etc. For more detailed information click here.
